Hi Chris,

I've seen this before if there is a service check that is hung, or rather not returning output, causing nagios not to exit.

Do you have other nagios processes left running after sending the sigterm via init script?  If so, it could be the culprit(s)..

You can also try upgrading to 3.0.6 but I see no mention of any bug like that in the changelog, so that may not help.. :\

Regards,
Jamie
